As of May 6, 2014, half of the United States was experiencing some level of drought. Nearly 15 per cent of the nation was gripped by extreme to exceptional drought. For the Plains and the Southwest, it’s a pattern that has been persistent for much of the past several years.
The map above was developed by the U.S. National Drought Monitor, a partnership of U.S. Department of Agriculture, the National Oceanic and Atmospheric Administration, and the University of Nebraska-Lincoln. It depicts areas of drought in progressive shades of orange to red. It is based on measurements of climate, soil, and water conditions from more than 350 federal, state, and local observers around the country. (NASA also provides experimental measurements and models to the drought monitoring effort.)
In a May 6 summary, Mark Svoboda of the National Drought Mitigation Center wrote of the Plains States:
Kansas continues to set the edge of the intense drought that seems to be waking up and pushing rapidly north along with warmer temperatures…Soil moisture and groundwater levels are hurting well in front of the peak demand season, as the cumulative impacts of such an intense multi-year drought are already glaringly evident…The story is even bleaker in the southern Plains, where the heat and drought are even more pronounced and entrenched across western Oklahoma and much of Texas as well…Streamflow and groundwater levels are hurting, given the long duration and sustained intensity of this drought, which is now going on close to four years.
The entire state of California is in some level of drought, much of it extreme to exceptional. Snowpack is 50 per cent of normal in many locations in the West, and Svoboda noted that a lot of snow has completely melted before it normally would.
Drought has had a serious impact on fruit and vegetable agriculture in California, and news reports sounded the alarm for grains and livestock in the Plains and South Central West. At least 54 per cent of the nation’s wheat crop is affected by some level of drought, as is 30 per cent of corn, and 48 per cent of cattle.
